Hello, my name is Andrei Maksimovich. I’m a Senior Full-Stack Mobile Software Engineer, and this website represents me and my company through which I provide B2B services to my clients.
I’m a passionate Full-Stack Mobile Software Engineer with over fifteen years of experience. I specialize in developing end-to-end mobile applications (Android/iOS/Mobile-Web) with backends powered by Node.js, AWS, Firebase. My expertise includes building mobile/web games, backend systems, CI/CD pipelines, business process automation tools, and third-party service integrations.
Over the last few months, I have been diving deep into iOS and macOS development. I believe native Apple platforms are where I can truly shine and fully utilize my experience, technical skills, and passion for delivering a polished user experience.
Why should you work with me? For several key reasons:
Product Ownership: I take pride in being responsible for my products. My goal is to build something meaningful, then polish and optimize it to provide the best possible experience. Quality, stability, and ease of use are my “turf” and my pride.
User Experience: I deliver intuitive UX, meaningful flows, and clean, simple UIs. I plan, execute, and refine every screen, interaction, and label to ensure a cohesive experience. I maintain consistent design and flow logic throughout the application to eliminate user confusion.
Deep Understanding: I build a comprehensive mental model for every project. Researching user requirements, business procedures, and workflows is a crucial part of my routine; I believe this foundation is essential for developing a superior product.
Lifelong Learning: I am never intimidated by a new language, platform, or framework. I dive deep into practice and experimentation until I can make educated decisions based on a true understanding of what is happening “under the hood.”
Expertise and Experience: Throughout my years in software development, I have built mobile applications, websites, and backends. I have configured standalone servers and auto-scaling clusters, and I’ve planned complex migrations. I have designed, resurrected, and optimized hundreds of systems. Whether a project is simple or complex, I approach it with the same dedication to planning, execution, and polish.
I have spent the last 10 years primarily in game development. During this time, I accumulated a diverse set of technical skills and experiences:
Networking: I have extensive experience with network code, managing latency and network inconsistencies, and working with various protocols and web/mobile-specific requirements.
Performance & Adaptability: Games require high-performance systems that remain flexible enough to adapt to a designer’s needs. This has shaped my “ground-up” analytical approach. I constantly evaluate how often code is called, how frequently it changes, and what level of optimization is required: whether it’s a “cold” or “hot”, or a system requiring low memory optimizations to maximize cache hits and efficiency.
Graphics & Rendering: I am proficient in working with GPUs and shaders, as well as handling complex rendering and calculations on mobile hardware.
Custom Tooling: I have designed and implemented dozens of custom tools, asset pipelines, build systems, and CI/CD workflows.
Multiplatform Development: I’m experienced in multiplatform development and web porting, with the ability to support both multi-threaded mobile and single-threaded web environments in a unified package. I am also experienced in designing and adapting interfaces for touchscreens, mouse and keyboard, and both small portrait screens and landscape monitors.
What I can do for you
Full-Stack Mobile App Development
I design and build complete mobile solutions that transform ideas into polished, production-ready applications.
- Cross-Platform Applications – I develop high-quality React Native apps that run on iOS, Android, and the mobile web from a single codebase.
- Native iOS & MacOS Apps – When needed, I build fully native applications with maximum performance and deep platform integration.
- Custom React Native Plugins – I create bespoke native modules for Android, iOS, and Web to extend React Native with advanced or unconventional functionality.
- Framework & SDK Integrations – I integrate third-party services, SDKs, and frameworks into new or existing React Native applications.
- Mobile Web Adaptation – I port existing mobile apps to the web, optimizing performance and UI for mobile browsers.
- Continuous Support & Feature Development – I provide ongoing updates, improvements, bug fixes, and major feature expansions.
- Backend Engineering – I build secure, scalable backend systems using Node.js, Spring-Boot, AWS, Firebase, and Linux servers to support mobile applications.
Business-Oriented Mobile App Development & Systems Engineering
I design, build, update, and maintain backend systems, internal platforms, and mobile applications that support and optimize everyday business operations.
- Custom Mobile Applications for Business – Not all apps are customer-facing. I develop specialized mobile tools for employees, partners, or clients, fully integrated into your existing infrastructure. These apps streamline workflows, improve productivity, and make field operations easier and more efficient.
- Data Import, Export & Migration – I provide support for transferring data between systems, platforms, or services. I ensure accuracy, consistency, and minimal disruption.
- Custom Tooling & Internal Systems – I build custom tools and automation systems that reduce manual work, eliminate repetitive tasks, minimize human error, and speed up business processes. From dashboards to importers, workers, and automated pipelines, I create solutions that fit your exact workflow.
If your business needs mobile tools, backend support, or process automation tailored to your specific operations, I provide the engineering expertise to make it happen.
Unity 3D Engineering
I offer full-cycle Unity engineering services for games, interactive applications, and cross-platform experiences.
- Core Gameplay Systems – I design and implement robust, scalable gameplay mechanics tailored to your project needs.
- Custom Unity Tools & Editors – I build production-boosting tools, custom inspectors, asset processors, and editor extensions.
- Asset Pipeline Engineering – I create automated pipelines for importing, optimizing, bundling, and delivering art and audio assets.
- Cross-Platform Porting – I port Unity mobile games to the web (WebGL) and other platforms, optimizing for size, performance, and compatibility.
- Performance Optimization – I improve framerates, memory usage, and responsiveness on mobile and web platforms.
- CI/CD Automation – I set up automated Unity build pipelines, cloud or local, covering testing, packaging, and deployment.
- Native Plugin Development – I build custom native plugins for iOS, Android, and WebGL to extend Unity’s capabilities beyond the engine.
- Native Framework Integration – I connect Unity projects with native platform code and third-party services (analytics, payments, sensors, system APIs).
- Backend Development – I create backend services to support live features, authentication, data storage, leaderboards, analytics, and game logic.
From small indie prototypes to production-grade, cross-platform applications, I provide the technical expertise to build, optimize, and scale your Unity-based products.
